T 0 allfwhom it may concern:

Be it known that I, EDWARD AUSTIN WAT- sy N, a citi/.en of the United States, residing a "nderson, in the county of Anderson and State of South Carolina, ,have invented cer` tain new and useful Improvements in Spinning Machines, of which the following is a specification.

The present linvention relates to controlling mechanism for-spinning machines, and more particularlyto means @whereby a small amount is wound at one end of the bobbin prior to the .full length windi'iig'foperation. It is ot the general type disclosed in my prior Patentv 1,350,905, issued AugustQ,

The object of the present inventioii is to provide relatively simple mechanism of a novel character that can be applied to 'a well-known type of apparatus, and will e'ffectively secure the desired sequence of operations.b l

ln the accompanying drawings Figure 1 is a view in elevation of the usual builder cam and builder arm, together with' the short-stroke mechanism constituting th'e This shaft extends longitudinally of the vided with an annular flange 23,' coiled. spring 2e. secured to the hub 22, is adapted to wrap thereupon and maybe attached asillustrated at 24 to the door on which the machine is placed;

A base 25, also fixed to the door, has an upstanding socket piece 26 in which is mounted a vertically7 adjustable standard 27,

and this standard is provided with a pawl 28 that operates on the ratchet wheel 19. Another socket member 29,. carried by the base 25, contains .a vertically adjustable standard carrying a reversely arranged pawl 31 located at a lower level than 'the `pawl 28 and adapted to engage with the ratchet. wheel 20 when the arm is depressed invention,

Figure' 2 is a perspective view of the mechanism,

beyond its ordinary working limits.

With this construction, i'fthe shaft. 16 is turned in one direction the bar 11 will be Figure 3 is a. and i A.

lFigures 4 and 5 are detail views showing the roller in active and in inactive relations to the short-stroke cam. f

In the embodiment disclosed the usual swinging builder arm is shown at 6 and is adapted 4to be operated in the usual manner by the main builder cam 7. Secured to this builder cam 7 is a short-stroke'cam 8. A bracket 9, adjustably mounted on the builder scam 6 by a bolt 10, which passes through a slot 11 in said bracket, constitutes a mounting for' a transversely sliding bar 11a. Journaled on theend of this bar is a roller 12 that is movable into cooperative engagement with the cam 8 to thereby effect la relatively7 short stroke of the builder arm 6. Upon the rearward movement otl the bar 11 the roller 12 will be disengagedfro said cam '8, leaving the arm 6 to be operated by the cam 7 in the ordinary manner. Y

- Another bracket 13 is adjustably secured to the 'builder arm by a bolt 14 and is provided with a box 15 in which i's journaled a front elevation of'the same,

moved to place the roller 12 beneath 4the cani 8, and therefore as said cam rotates it will be evident that a short stroke will be given to the builder 'arm 6. Upon each depressionm of the arm the pawl v28 will operate on the ratchet wheel 19, thereby turning the same' and the sha-ft 16 step-by-step, until the rollerI 12 is withdrawn from the cam 8. Upon its disengagement the spring 24C acts upon the shaft to iriovezthe bar 11a to its limit, such limit being determined by a stop pin 32 that abuts against the bracket 9. The cam 7 then operates on the builder arm 6 in a manner readily understood. To return the partsit is only necessary for the arm 6 to be depressed suiiiciently to cause the pawl 31 to engage the ratchet wheel 20, whereupon the shaft will be turned in the opposite direction andthe bar 11 moved longitudinally to cause the roller 12 to again engage beneath the cam 8.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will -be apparent to those skilled'iii the art', withstood tri-at various changes in the size, shape,

proportion and minor detalls of construction. may be resorted to without departing from.

the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is:

l. In apparatus of the character set forth, the combination with a builder arm and means for normally operating the same, of a supplemental cam, a. device'movably mounted on the arm l and engaging the supplemental cam, a ratchet wheel on the arm geared to the device, and a pawl in the path of the ratchet wheel and effecting its rota- 'tion as the builderarm moves. I

2. In apparatus of the character set forth, the combination with a builder arm and means for normally operating the same, of a supplemental cam, a device movably mounted on the arm and engaging the supplemental cam, a shaft journaled on the arm and geared to the device, a ratchet wheel fixed to the shaft, and a pawl in the path of the ratchet wheel andeffecting its rotation as the builder arm moves.

3. In apparatus of "the character set forth,

.the combination with a builder arm and a pair of cams for respectively operating the same, a reciprocatory rack bar on the arm having means for engagement with one of the cams, a shaft journaled on the arm and having a pinion engaged with the rack of the bar, a ratchet wheel on the shaft, and a pawl located in the path of the ratchet wheel to operate it as the arm is swung.

4. In apparatus of the character set forth, the combination with a builder arm and means for normally operating the same, of a supplemental cam, a devicemovably mount ed on the' arm and engaging the supplemental cam, means for effecting a gradual withdrawal of the device from cooperative.

engagement with the cam, and-means for effecting a further' movement of the device .after its disengagement from the cam.

5. In apparatus of the character set forth, the combinationl with a builder arm and means for normally operating the .same,' of a supplementall cam, a devicel movably mounted on the arm and en aging the supplemental cam, means for e ec'tirig a grad# ual withdrawal of the device from cooperative engagement with the cam, and a spring for effecting a further and accelerated movement of the device after its disengagement from the cam.

6. In apparat-us of the character set forth,

the combination with a builderarm and a pair of cams for respectively operating the same, a reciprocatory rack bar on the arm havmg means for engagement with one of the cams, a shaft journaled on the arm and having a pinion engaged with the. rack of the bar, a ratchet wheel on the shaft, a pawl located inthe path of the ratchet wheel to operate it as the arm vis swung, and a spring engaged with the rack shaft to further turn the same when the device is disengaged from the cam. f

7. In apparatus of the character set` forth, the combination with a builder arm, of a pair of cams for respectively operating the arm, a device movably mounted on the arm and movable into and out of engagement with one of the cams, means for automatically effecting the disengaging movementof the device, and means for automatically effecting the reengagement of the device with Y the cam.

8. In apparatus of the character set forth, the combination with a swinging builder arm, of a pair of cams for res ectively operating the arm, adevice mova lymounted onthe armand movable into and out of engagement with one of the cams, means for automatically effecting the disengaging movement of the device upon the normal swinging movement of the arm, and means for automatically effecting the reengagement of the device with the cam upon a greater.

predetermined movement of the arm.

9. In apparatus of the character set forth, the combination with a builder arm, of a pair of cams for respectively operating the arm, a device movably mounted on the arm and movable into and out of engagement with one of the cams, a shaft journaled on vthe arm for moving the device, and devices ment with one of the cams, a. shaft journaledv on the arm for moving the device, oppositely arranged ratchet wheels in the shaft, andA vp'awls for respectively operating on the wheels, one of said pawls being normally disengaged fro-m its wheel.

In testimony whereof, I affix my signature in the presence of two witnesses.
